For each enemy you kill, you get credits. But, here's my problem : I don't know how to make the 2 enemies spawn only after the THREE enemies are dead. I know how to make a npc spawns after another npc is dead : NPC_target. But how can I make this npc (or these npcs, in my case) to spawn ONLY after the THREE enemies are dead, and not just one. So : Once you've killed the enemies, 2 other enemies spawn.
